Aaron Hernandez has filed a grievance seeking payment from the Patriots on guaranteed base salaries, according to multiple reports.

The NFLPA, on Hernandez's behalf, is seeking payments of $1.323 million in guaranteed 2013 base salary and $1.137 million in guaranteed 2014 base salary, as well as $500,000 for a guaranteed 2014 workout bonus.

Hernandez also filed a grievance, again through the NFLPA, seeking recovery of the final installment of his $12.5 million signing bonus due in March, which is worth $3.25 million.

Our pals at Pro Football Talk have some more insight into the grievance here. Among their observations:* In the aftermath of Hernandez’s arrest for murder and release from the Patriots, those at the NFLPA believed that Hernandez would be unable to recover his otherwise guaranteed base salaries for 2013 and 2014. They've clearly changed their minds. * Since the amounts were guaranteed and Hernandez was cut, the union is arguing that he deserves his money.* The Patriots will argue that they cut Hernandez -- as PFT writes -- "pursuant to paragraph 11 of the standard player contract, which permits termination of employment when the player 'has engaged in personal conduct reasonably judged by Club to adversely affect or reflect on Club,' the guarantees evaporate."

* Hernandez has a better chance at winning the second grievance. "The money was earned when he signed the contract in August 2012," PFT writes. "The only potential argument against paying him hinges on whether he is charged with — and convicted of — the July 2012 murders of Safiro Furtado and Daniel Abreu. If he signed the contract knowing that he had murdered two people, there’s likely a potential legal argument that, if successful, would void the deal."* Furtado, Abreu, and Odin Lloyd's families should hire representation and demand that any proceeds from these grievances (up to $6.21 million) be held pending the outcome of the wrongful death lawsuits against Hernandez, PFT explains. "If they don’t," PFT writes, "any money recovered by Hernandez could be long gone by the time the civil litigation ends."
